Core technical advantages
Energy capacitance:
High-performance film capacitors are selected. The continuous working life can reach more than 100,000 hours, and the withstand voltage level is 55kV. The capacitance value is relatively small 3.0nF, and the secondary leakage current is small, which ensures the safety of the test equipment and the secondary circuit.
Conversion Transformers:
Our company independently designed and manufactured, the output power is stable, and it can work continuously for a long time without heating under the condition of 1.2 times the rated voltage. Long service life and stable online. In the case of impact and short circuit, the product has low calorific value and long anti-short circuit current time.
Protection Circuit Module:
Our company designs and manufactures independently. The secondary circuit is protected against overcurrent and overvoltage, and does not overlap with the voltage level of the withstand voltage test. The core components work directly, which avoids the frequency and life problems of conversion components such as relays, and is more stable and reliable on the line.
